    Is this primary or secondary hypogonadism?

    I'm a couple weeks into TRT now so that decision has been made, however I am wondering how I would be classified based on these labs. I took some tests twice, about a week apart, to verify the results. I'm a high SHBG, low Free T type of guy, with an elevated FSH. I haven't been able to find...

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
